SHOCK-'ABSRBNG ilECi-IANISM FOR AUTOMOBILES.

Applientonuled Merch 31, 1927. e Seri-i No. 179,862.y

uThis `invention .relates to Shock absorbing mechanisms 'for automobiles.

An object ol the invention is to provide :r

the vehicle andthe lree end portion et Suid member disposed in e, lgroove or guide-'wey formed in ineens Secured to the iiirnnie ot the vehicle, the engeging` surfaces olf the guidewzify beine* arranged so ne to bringf nbout deflection oil the resilient member and develop combined irietionnl and resilient resistance to the relative movement olf the freine and axle.

Other and further objects ot the invention will more clearly nppezir ltrom the description and cleim hereinafter iollowing. y

1n the drawings, forming :i part oi this Specieation, yFigurer view of the Viorwnnrd portion oi n vehicle chee-A sis, axle, und Spring, end showing the invention applied in connection therewith. Fig,"- ure 2 is n n transverse vertical sectional view through the lriune und Spring' inen'iber, and showing' e rear elevation ot ythe invention,

' stantinlly on the line 2 2 of Figure 1. 11nd Figure 3 is n side elevational view ein. frag- `ment of a Vehicle, similar 'toFigure 1, und showing a different embodiment oit `the invention.

As shown in the drawings, 5 denotes the ttorwerd portion of one side i'rnne oit :i vehicle, 6 designates the 4axle oit the vehicle, :rnd 7 the ueual lent Spring assembly which is securedto the :lli-une by suitable menne ne et the pointe S-e. f n

The Spring` nseembly 'l' beers upon the npper surface el the axle 6 und is secured in position by ineens oi a. pair o1 U-shnped bolts 9 which have threaded ends extending through the upper flanges oi the axle, said 1 is :L Side. elevational seid sectional view being teken Sub-y clamping bolts beingI secured in position by Suitable .nnte which bear upon the under surineen olf the flanges en the axle. I

Secured to the under sur'lnce oi: the axle ie e, U-sheped friction element having n bight portion 11, `and upwardly extending legs y12--12. The bight portion 11 ot the friction element is held in poeition by clamping memhere` 13H13 end 11i, the latter ot which is in the tiform oi n plete, littinp; along the under Surface oi the bight portion 11while the demping members 13-13 bear against the lower tien ot' the znrle member 6,the niember 3 13 and 141. being Secured together by bolo' indicated :it 15 15. The big'ht portion 11 :ind legs 12-12 oli the friction element :ire integrally termed, und'the ent-ire element is preterabl y mede up oit ltempered. swingsteel.

Secured to the outer side oi? the treme member 5 by menne oi.E rivets 16-16 is n plate 17 having n laterally extending post 18 thereon. Pivotnlly mounted upon the post 18 iS n, housing; 1S), comprising n body portion 2O which iits over the poet 18, und is Secured in position thereon by menus of :i Cotter pin 21, between rdown wnrdly diverging portioneI 223-23, each ol which is provided with :i groove indicated 113211, eonverging` upwardly and extend ing enti rely throu gju the'body portion 20 of the housing', the grooves orehennele 24 being adapted 'lier the reception oi the en de oi" the legge 12-12 oit the U-slinped friction element.

1n operetion, assuming approach of the axle member G and treme member 5, the housing 19 and the Uehnped member will be moved toward each other, and by reason ot the tact that the engaging Surfaces provided by the Wells of the `groeven 24 :1re out of line with the line oit movement oit the legge 12--12 ot the U-shiiped member which would occur y disposed if'erticitlly extending zircnste "grooves ell-fil, the lower ends oli which ei;-

Aixed to the top surface of the axle 32 is n bracket Sil, having side portions riveted to the u i ier iinn'es of the axle The bracket n v 1 o Y U 34: is `rovided Witn u istnnding lu o's 8o onlv -1 v n k D 7 a u one of ivlncii shows iii Figure butJ it Will be understood thattivo spaced luf-Ys' fire provided, and extending tliiougii tne lugs is n pin 36. Disposed beneath the pin 35 is the bight portion 3T ol n 'l`riction-eleinent, the legs 38-3S of the friction element eiending upwardly as shown. Mounted on the freine 30 is a. )late hei-'ine' n oost 39.'uoon Vwhich is pivotzillvhiing the housing 0, the housing beino' secured in iosition b i cetter a c; 1 l Vpin and `Wrisher in trie seine manner es described in connection "with Figures ll and 2. The housing el@ is provided with oppositely slots or tend at :i tangenteto the arcs, the grooves rl1-1l each being adapted 'for the reception of one of the legs 38-38 oit the U-sliiiged friction member. In operatien, relative ginovenieiit of the freine member 30 and axle member Qelects travel of the legs 23S-3S of the friction element in the grooves of the Y .L A L housing T-O and due to Vthe disposition oi' the Walls delining the'groovesfin a direction out `shaped resilient of line with the movement of the friction element which would take place but for engagement vwith the Wells of said grooves combined rictioiinl and resilient resistance is set up against relative nioveiiients of the parts.

lVliile I have herein shown and described what l consider the preferred ninnner of carrying ont the invention, the saine is merely illustrative, and I contemplate all changes und modifications which come Within the scope or" the claim appended hereto.
